If you’re an athlete, runner, or fitness fanatic, the Apple Watch is one of the most convenient fitness tracking devices out there. You can use it to track your daily exercise routine and see how you’re improving over time. But did you know that the watch can also be used to help monitor your blood oxygen levels? It’s true! And using the Blood Oxygen app on your Apple Watch can help you reach peak performance in whatever activity you choose to do. Here’s how to use it.
What Is The Blood Oxygen App?
The Blood Oxygen app will display your percentage of oxygen saturation and heart rate in real time. This means you can use your watch as a personal pulse oximeter while keeping track of other vitals like heart rate, beats per minute, body temperature, and more. You can also find out your blood pressure reading as well if you buy a compatible blood pressure monitor for just $30.
The best part about using this app is that it has been clinically proven accurate when used with our proprietary skin sensor. As long as you have an Apple Watch, a compatible phone and the Blood Oxygen app installed on both devices, you’re ready to get started. To open the app on your watch, simply go to Settings > General > Digital Crown > Applications. Next, scroll down until you see Blood Oxygen and select it. Once opened, swipe left or right until you see either Pulse or SpO2. Tap Pulse to measure your blood flow through your wrist by measuring your heart rate.
Tap SpO2 to measure how much oxygen is in your bloodstream. If both these features are active then a green checkmark will appear next to each option- so swipe left or right until they are no longer active and tap the one you want again (for example SpO2).
How To Set Up The Sensor
- Go to Settings on your iPhone and tap General.
- Tap Privacy and scroll down to Blood O2 Meter.
- Tap it, then tap Start Measuring Pulse, and give it access.
- You’ll want to calibrate the sensor each time you measure your blood oxygen, but you only need to do this once a day for accuracy and consistency. To calibrate your finger tip, press against it until the button turns green then wait ten seconds before pressing again — this will give you an accurate reading of 90-100% blood oxygen content in your body.
- If you’re using a pulse oximeter without an app, follow the directions that came with your device.
- If you’re using a pulse oximeter with an app: -Choose Settings from the main menu and turn on Enable Sensors. -Tap Measure My Pulse, then My Heart Rate, and finally Blood Oxygen.
- Place your index or middle fingertip over the sensor until it lights up green, then hold steady for 10 seconds. The app will display your heart rate and blood oxygen level in real time as they change; they should look something like this
- The app displays your current pulse rate in beats per minute (bpm) and your average respiration rates per minute (RPM).
- Below these readings is your percentage of arterial saturation (SaO2), which is shown as a percentage (%) between 0% – 100%. SaO2 is generally around 94%, but when exercising it can drop below 60%. At lower levels, symptoms such as lightheadedness, chest pain, palpitations, dizziness, anxiety attacks or difficulty breathing may be experienced. It’s important to note that these symptoms are not specific to low SaO2 levels alone; other health conditions may also cause them at any given time without causing low SaO2 levels too.
How To Read Your Results
Your device will automatically measure your pulse rate and display your heart rate variability (HRV) measurement, which can be a good indicator of how well you are managing stress. HRV is measured in units called Segments, or segments per minute (SPM). For most people, the HRV value falls between 8-12 SPM. You can set goal for yourself by customizing which segment you want to hit.
You’ll also see your respiratory rates displayed in liters per minute (LPM). LPM readings should be less than 20 LPM at rest and less than 25 LPM during activity. Readings above these values may indicate that you have an overactive thyroid gland, bronchitis, emphysema, or another lung disease.
The green line next to your HRV reading indicates whether your current resting breathing rate is within the range recommended by The World Health Organization’s international guidelines: 12-20 breaths per minute. Once you’ve had time to explore all of the data your device has recorded, tap Done at the top right corner of the screen.
If you forget what any of this means, don’t worry! You can always tap back through each screen and review all the details from previous readings so that you’re ready for your next checkup. To get started, just download the app and open it on your phone!
How do I know if my breathing is shallow? Shallow breathing can cause an oxygen deficiency in your blood. The Blood Oxygen app on your Apple Watch monitors your Breathing and displays how shallow or deep it is, so you can identify and correct it.
– How does the Blood Oxygen app work? The app monitors both heart rate and Breathing with a light beam that measures oxyhemoglobin saturation. You simply need to open the app, slide over to the Breathing tab, then wait until you feel your natural breath coming in and out of your body. Once you see your breathing as normal, press Start Measurement. As soon as your Breathing stabilizes at the normal level, press Stop Measurement.
– What is the difference between shortness of breath and shallow breathing? Shortness of breath usually means that there’s too much carbon dioxide in your lungs for them to function properly; this happens when you’re exerting yourself or feeling anxious. Shallow breathing causes an oxygen deficiency in your blood because there’s not enough air reaching all parts of the lungs; this happens when you’re experiencing anxiety or feeling depressed.
– What should I do if my Breathing seems irregular? Irregular Breathing might be a sign of sleep apnea, which may require medical attention. If you notice any changes in your Breathing pattern, consult your doctor.
– Is there anything else I should keep in mind about using the Blood Oxygen app? For accurate results from the sensor on your Apple Watch, make sure that you don’t wear any other metal objects (such as jewelry) or clothing with metal zippers near the sensor area during measurement. Also make sure that you place the sensor under direct contact with skin while measuring.
